Old Denmark Tool & Die knife

[CMUtuba]

my father (who usually mocks my "obsession" with sharp objects) gave me a cool knife today. This belonged to my great grandfather, and that is all I know about it. The side says "DENMARK KNIFE & TOOL CO. Phone Redford 5700" The pictures are to try to show how it opens. in the open position, it is locked, not that I feel it is necessary for a tool of this size. The blade is only 1.5 inches long. If anyone has info on this knife or others like it, that would be awesome.

I've never seen one of those before, but surely an interesting little piece..

They're flip knives; the writing on the scale is just one example of many logo and advertisement runs done on those knives.  I have a couple of them in different sizes.

Neat! I've seen them for sale before, but never handled one. So was it made by DENMARK KNIFE & TOOL, or are they just the company being advertised?

[Sazabi]

I have no clue; I think Colonial made some, but I don't know for certain.

I've only ever seen another one like it on the tinternet but I wondered if they would be useful in practice or not?

The blade is REALLY thin(half the thickness of my micra blade), so it is really only useful for very light use. I think this one will make a nice letter opener if nothing else.

A. G. Russell sells one. They even admit that it's based on old advertising knives. It's a cool design. http://www.agrussell.com/ag-russell-funny-folder-aluminum-and-aus-8/p/RUShhhFF3AL/
